Title:
TONER FOR DEVELOPING ELECTROSTATIC LATENT IMAGE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/179357
Kind Code:
A1
Abstract:
A toner for developing an electrostatic latent image contains a plurality of toner particles that contains a crystal resin, a non-crystalline resin and a plurality of release agent domains. The number of the release agent domains with a dispersion diameter between 50 nm and 700 nm in the cross-section of the toner particles is between 15 and 50 per toner particle. The overall area of the release agent domains with a dispersion diameter between 50 nm and 700 nm in the cross-section of the toner particles is equal to between 5% and 20% of the cross-sectional area of the toner particle. A diffraction intensity at a Bragg angle 2θ of 23.6° is between 13000 cps and 17000 cps in the x-ray diffraction spectrum of the toner, and a diffraction intensity at a Bragg angle 2θ of 24.1° is between 20% and 40% of the diffraction intensity at a Bragg angle 2θ of 23.6°.
